Title: Data storage cathode ray tubes
IPC: H01J9/233
Filed: 1971-04-19
Abstract: 1329917 Cathode-ray storage tubes; semiconductor devices SIEMENS AG 19 April 1971 [23 April 1970] 26863/71 Headings H1D and H1K In a cathode-ray storage tube having a target comprising insulating spots or areas less than 1 micron thick on a conductive or semiconductive signal plate, the writing speed is increased by reducing the capacitance of the spots, either by under-etching the insulating layer or by providing a deflection zone beneath each storage element. The signal plate may be silicon, tantalum or aluminium, and the insulating spots may be oxide of the plate material. In one example, Fig. 2 (not shown), insulating spots are provided on a silicon plate in known manner, and the signal plate is etched through the interstices to leave each spot supported by a thin pillar. In another arrangement, Fig. 3 (not shown), apertures are provided regularly in a continuous insulating layer and the substrate is etched through these apertures to leave the layer supported by thin columns. In a final example, Fig. 4 (not shown), the substrate may be N-type silicon which has a weakly N-doped depletion zone below each insulating spot. The tube may use a single beam for recording, readout and erasure, with different potentials applied to the signal plate for each process; the stored charge may be positive or negative according to the signal plate potential in the recording process.

Title: Improvements in or relating to a controlled self-locking sealing device between two parts of a structure or two structures
IPC: B60P1/64
Filed: 1965-06-24
Abstract: 1,111,141. Hatch covers. MACGKEGORCOMARAIN. 24 June, 1965 [25 June, 1964], No. 26894/65. Heading B7S. A self-locking sealing device between a hatch cover section 4 and the coaming 2 of a ship's hatch 1 comprises a flexible, resiliently deformable tube 13 attached to the faces 11 and 12 of the angle section 10 attached to the coaming ledge 3. In the deflated state of the flexible tube 13 the hatch cover is free to move on rollers 5 along the coaming ledge. In its hatch covering position, rollers 5 of the hatch cover are supported by platforms 8 flush with the runway in openings 9. Locked fluid tight closure is achieved by dropping platforms 8 and inflating flexible tube 13 through introduction of an hydraulic or pneumatic pressure fluid. In its expanded state tube 13 strongly applies itself against the adjacent surfaces of the coaming and the cover. Similar self-locking fluid tight closure is achieved between adjacent, rolling hatch covers and between cover sections hingedly interconnected and foldable.

Abstract: 992,606. Driving belts. ARBEE CORPORATION. July 10, 1963 [July 31, 1962], No. 27262/63. Heading F2Q. The overlapping links 10 forming a driving or other belt are secured together by locking tabs 11 integral with the links, each link having a tab 11 and two or more apertures 26, 27 receiving the tabs of preceding links. The links may be trimmed before or after assembly to give a smooth V-belt formation with parallel edges. The links 10 are tapered from one or other end 21, 22 according to whether the tabs 11 are to lie on the inside or outside of the belt. In the various forms of assembled belt air between the belt and pulley is vented through the aligned apertures, thereby ensuring a proper fit, promoting cooling and reducing noise. The links may be made of corrosion-resistant elastomer or other material such as a polyester fabric or neoprene.

A core-box comprises channel members 10, 11, Fig. 1, interconnected by links 12 which allow member 11 to move down until its flanges abut the flanges of member 10. Spring bolt 22 holds the members in position shown, and a compressed-air vibrator 16 drives the box into the ground. To raise the box, bolt 22 is withdrawn and cable 37 is hoisted to raise member 10 causing member 11 to move thereagainst and hinged flap 30 to drop to a horizontal position thereby retaining the core in the box. Seals may be provided between the abutting flanges. In other arrangements, the flanges here interengaging formations or overlap. The members may be formed of semi-circular, semi-hexagonal, or angle section instead of channel section material. In another embodiment, a weight 52, Fig. 5, is used to drive the core-box, and one of the interconnecting links is extended by arm 56, whereby members 10, 11 are positively moved together as the box is hoisted by cable 57.

Abstract: 664,028. Pitch and tar. FARRER, J. O. (Gaz de France-Service National). Oct. 24 1949, No. 27299/49. Class 55 (ii). [Also in Group V and XIII] Molten pitch or the like is cooled, solidified and broken up by running it on to the lower portion of an inclined belt con. veyer 1 which is troughed by idling rollers 2 and at the same time running water down over the ascending pitch. The pitch is fed on to the conveyer at 3, the belt carrying it, in the form of a ribbon, below the surface of water which collects at the lowermost point C in the belt travel and then up an inclined portion thereof. Water is sprayed on to the ribbon of pitch at 4 and is distributed over its surface by brushes 11 and 12. At the head of conveyer 1 the pitch is cool and solid and passes from the conveyer on to a second belt 5, an air jet 7 in the space between the belts removing any excess water. The pitch falls in pieces from the end 8 of belt 5 on to shoot 9.

Title: Improvements in or relating to welt grooving and bevelling machines
IPC: A43D8/48
Filed: 1924-11-22
Abstract: 247,669. British United Shoe Machinery Co., Ltd., Swales, G. P., and Minett, W. T. Nov. 23, 1924. Splitting - apparat u s ; stationarycutter apparatus.- Welt-splitting means are added to a machine of the type described in Specification 109,837. The splitting-knife 2 is mounted on a support 3, carrying a presser roll, which, with a work-supporting roll 1 is held in the horizontallymovable carrier slide 4. A welt to be split first raises both the roll 11 and the knife 2 against the urge of a light spring 5, until an abutment on the support 3 contacts with an adjustable screw 13 on the carrier, and it then raises alone the roll 11 against the pressure of a strong spring 9. The grooving-knife 15 is fixed to a slide 16 laterally adjustable in an arm 17 pivoted on a pin 18 to the machine frame. An adjustable rod 20 connects the arm 17 to the carrier-slide 4. The distance of the pin 18 from the rod 20 is three times its distance from the knife so that when the carrier slide is moved the grooving-knife is moved automatically one-third of the amount in the same direction. A bevelling knife 22 is secured to the upper end of a rod 24, the axis of which passes through the knife edge, pivoted in a bracket 25 laterally adjustable on the slide 4. The knife is swung by a spring against a knife-edged stop 30 on the slide 16 so that the bevelled edge of the welt is prevented from extending behind the groove. A freely rotatable roll 50 is mounted on, and projects through, a stationary guide 23 on the carrier 4 to support the underside of the welt during splitting, and an extension of the guide 23 supports the workpiece for bevelling and grooving. The welt is guided past the knife 2 between an edge gauge 31 on the roll-support 8 and a guide 32 adjustable laterally of the strip. A guide face on the support 23 and a face on the guide 32 position the welt by a crowding action during bevelling.

Group x may be for example an ether, ester, urethane, sulphide, amide, imino or siloxane linkage. The water soluble polymer is preferably a polyether, especially a polyalkylene glycol such as polyoxyethylene glycol. The end groups are derived from, for example C 14-22  alkyl isocyanates or a carboxylic acid containing a C 14-22  hydrocarbon residue such reactants being condensed with the terminal OH groups of the polyglycol. Those additives preferred are di-C 18  alkanoic acid esters of polyoxyethylene glycol of M.W. 6000. The levelling agents are used in amounts of 0À1- 3 wt. per cent based on the solids content of the latex. They are particularly suited for addition to addition polymer dispersions. In the examples acrylic latexes, polyvinylacetate latexes, and styrene/butadiene copolymer latexes are treated with levelling agent selected from the following diesters of polyoxyethylene glycol: distearate, diisostearate, di-(C 16-19  mixed neoalkanoic acid) ester, dioleate, dilaurate) and di-(C 21 H 43 COOH) ester; polyoxyethylene glycol distearyl ether; polyoxyethylene glycol distearyl urethane; and the distearyl ester of a polyoxyethylene/polyoxypropylene block copolymer.
